PRIMARY TIME LINE FOR APRIL 20, 1999
From the beginning of the investigation into the
shootings at Columbine High School, a timeline was established to record the
significant events of April 20, 1999. The
timeline was updated several times as new information became available from all
the different sources. The result
is a Primary Timeline, which offers a brief chronological account of the events
of April 20, 1999, the movements of Eric Harris and Dylan Klebold, the law
enforcement and emergency responses and the media coverage.
This timeline is the basis for a more detailed, comprehensive timeline of
the April 20 events that is included in this report.
